Calibrating your spectrometer has never been easier: the AvaLight-HAL-CAL-Mini and Avalight-DH-CAL are NIST traceable calibrated light sources to measure absolute spectral intensity.

The AvaLight-HAL-CAL-Mini is a com-pact, affordable light source. It is cali-brated for the visible range (350-1095 nm). Optionally, an extended calibra-tion for the near-infrared spectral range (1100-2500 nm) can be ordered. It has a built-in diffuser, a cosine cor-rector with SMA adapter and comes with a calibration file in ASCII format.

Calibration can be done using the AvaSoft software.

The AvaLight-HAL-CAL-ISPxx-Mini is a special version of the Avalight-HAL-CAL-Mini, which enables coupling any of Avantes’ AvaSphere-xx-IRRAD integrating spheres to the lightsource (xx=30, 50 or 80) for calibration. This source is supplied with a special bot-tom plate to stabilize the AvaSphere. The Avalight-HAL-CAL-Mini and Avalight-HAL-CAL-ISPxx-Mini include a power supply.

For radiance calibration in the visible spectral range (360-1100 nm), Avantes offers the AvaSphere-50-LS-HAL-CAL. This radiance calibration sphere is nor-mally used to calibrate a spectrometer and a bare fiber with an SMA connec-tor. This uniform source ensures that the fiber is homogeneously illuminated during calibration.

The AvaSphere-LS-HAL-CAL is supplied with a power supply and a CD-ROM with the calibration file in ASCII-format.

For calibrations in the ultraviolet and visible range (200-1099 nm), the AvaLight-DH-CAL is the best solu-tion. This source can be used with all AvaSpec spectrometers to calibrate for absolute spectral intensity. It is supplied with a built-in diffuser, a cosine corrector (CC-VIS/NIR) with SMA adapter and a CD-ROM containing the calibration files in ASCII format.

Two calibration files are included: one for irradiance calibration over the full range (200-1099 nm) and one over the visible and near infrared range (350-1099 nm). For the first file, both the deuterium and the halogen bulb should be used during calibration. The second file is to be used with only the halogen light. The halogen only spec-trum provides a smoother black body

calibration spectrum for the longer wavelengths.

For a more balanced spectrum accross the 200-1100 nm range, Avantes offers the AvaLight-DH-BAL-CAL. For ultra-violet range calibration only (200-400 nm), the AvaLight-D-CAL is the right choice.

The calibration files can be imported in the AvaSoft-IRRAD application soft-ware, for intensity calibration which turns your spectrometer into a spectro-radiometer.

The AvaLight-DH-CAL-ISPxx is a spe-cial version of these calibrated light sources, meant to facilitate coupling of the AvaSphere-xx-IRRAD integrat-ing spheres to the light source. (xx is

30, 50 or 80). The AvaLight-DH-CAL, AvaLight-DH-BAL-CAL and AvaLight-D-BAL-CAL all include a power supply.
